Operating frequency band of 148 and 172 MHz enables easy implementation of radio repeater telecommunications systems. Our company offers to the market new unique collinear antenna, designed specifically for use in 148/172 MHz telecommunications systems. It has two resonance points at the frequency band of 148-149 and 171 172 MHz (insignificant factory readjustment is allowable). Two active dipoles, jacketed into durable fiberglass radome, provide 3 dBd gain due to phasing. Thus you can make perfect single or multichannel antenna-feeder circuit with circular radiation and high selectivity and decoupling level between TX and RX circuits using this antenna together with duplexer DPF5-3V, DPF2-6VM or MDF-6VM.
